TONGUE RATIO CALCULATION IN EXTRUSION DIE DESIGNThis calculation will supply a value in the form of a ratio between the opening (or neck) ofa tongue detail to the total surface area of the tongue itself. The calculation will supply anindication as to the strength of any such tongue and the likelihoo

Die Block Caused by Relief DesignThe working belt without support is easy to deform and crack when the relief is too large. Profile in the export stage of the material head out of the working belt due to the flow speed, wall thickness, resistance and other reasons, not necessarily radial outflow, m

Welding Processing in Die CorrectionIf the velocities between the outside of the profile and the central portion are close tobeing equal and the pressure within the die is great enough then a eutectic weld between consecutive billets will be achieved. The outer friction, as already discussed, is gen
